Test Code Sickle Phen Sickle Cell Phenotype (Rh & K) PSBC

Important Note

If the patient has been transfused in the last three months, antigen typing of patient red cells may yield unreliable results due to the presence of donor cells. A pre-transfusion should be used for antigen typing, if available. Sample will be referred to red cell genotyping for other blood group antigens. RBC genotyping can provide this information in recently transfused recipients.
